Decompressing is done by calling the [`Decompress1X`](https://godoc.org/github.com/klauspost/compress/huff0#Scratch.Decompress1X)

or [`Decompress4X`](https://godoc.org/github.com/klauspost/compress/huff0#Scratch.Decompress4X) function.

For concurrently decompressing content with a fixed table a stateless [`Decoder`](https://godoc.org/github.com/klauspost/compress/huff0#Decoder) can be requested which will remain correct as long as the scratch is unchanged. The capacity of the provided slice indicates the expected output size.
|

|

You must provide the output from the compression stage, at exactly the size you got back. If you receive an error back
|
||||
your input was likely corrupted.

@ -309,6 +323,20 @@ The decoder can be used for *concurrent* decompression of multiple buffers.
|
|||
It will only allow a certain number of concurrent operations to run.
|
||||
To tweak that yourself use the `WithDecoderConcurrency(n)` option when creating the decoder.
|
||||
|
||||
### Dictionaries
|
||||
|
||||
Data compressed with [dictionaries](https://github.com/facebook/zstd#the-case-for-small-data-compression) can be decompressed.
|
||||
|
||||
Dictionaries are added individually to Decoders.
|
||||
Dictionaries are generated by the `zstd --train` command and contains an initial state for the decoder.
|
||||
To add a dictionary use the `WithDecoderDicts(dicts ...[]byte)` option with the dictionary data.
|
||||
Several dictionaries can be added at once.
|
||||
|
||||
The dictionary will be used automatically for the data that specifies them.
|
||||
A re-used Decoder will still contain the dictionaries registered.
|
||||
|
||||
When registering multiple dictionaries with the same ID, the last one will be used.
|
||||
|
||||
### Allocation-less operation
